From the Port of Kos: Full Day Boat Cruise to 3 Islands

The best part of this $35 island cruise is the mix of scenery and easygoing sea time. You’ll enter Vathi’s fjord on Kalymnos, stop for swims in clear water, and visit Pserimos before sailing back to Kos. The friendly Odyssey crew, led by Captain Yanas, keeps the day moving without turning it into a loud party boat.

I like the excellent value, since lunch, island stops, and swimming are included for less than many short boat excursions. I also like the chance to spot dolphins near the fish farms, a lucky extra that has made several days memorable. The main consideration is space: the boat can feel crowded at busy times, and wind may change a planned stop.

Key points to know before booking

• Vathi gives you a quick look at Kalymnos life: You get time to walk through the quiet village, take photos of the fjord, and try local specialties.
• The swimming stops are the day’s main event: Plati and the surrounding coves offer clear water and a chance to jump straight from the boat.
• Dolphins are possible, not promised: The route passes fish farms where wild dolphins are sometimes seen close to the boat.
• Lunch is simple, filling, and included: Expect souvlaki, salad, tzatziki, and bread, with beans and dolmades for vegetarians.
• This is a relaxed cruise, not a party boat: Music plays onboard, but it is generally kept at a comfortable level.
• Bring cash for Pserimos: Card payment may not be accepted at restaurants on the island.

Why this Kos boat trip is good value

At $35 per person, this is one of those outings where the price matters as much as the scenery. You are paying for a long day on the water, transport between three islands, lunch, and several chances to swim. Drinks cost extra, but onboard prices are described as reasonable, with cocktails around €6 and bottled water available at a low price during happy hour.

That makes the cruise a practical choice if you want to see more of the Dodecanese without arranging separate ferries. You can sit back while the Odyssey handles the route, meals, and timing. The day is not built around long guided talks or major monuments. It is about sea views, short island visits, swimming, and the pleasure of letting someone else steer.

The boat leaves from the Odyssey vessel in Kos harbour, opposite the Port Police. Look for the blue boat named Odyssey and arrive by 9:30 to check your ticket. Hotel pickup is not included, so you need to make your own way to the harbour.

The scheduled duration is 450 minutes, or 7.5 hours. Actual timing can shift with wind, sea conditions, dolphin sightings, and docking arrangements. That flexibility is useful when wildlife appears, but it also means your time at an island may be shortened if the captain makes an unscheduled turn or detour.

Sailing from Kos toward Kalymnos

The first sailing section takes about an hour. This gives you time to settle into your seat, listen to the onboard music, and watch Kos recede across the water. Seating is described as comfortable enough for the duration, though the boat may feel full on popular dates.

Try to choose your spot with the sun and wind in mind. The front can offer the best view, but rougher water may leave you soaked. The middle and rear areas may be easier if you want a calmer ride or prefer to stay near the bar and lunch area.

The music is part of the atmosphere. It is not presented as a high-energy pirate cruise, and the volume is generally comfortable. If you want traditional Greek music throughout the day, you may find the playlist less specific than expected. Still, the overall mood is meant to be relaxed, with music providing a backdrop rather than taking over the trip.

The crew is a major part of the experience. They are described as friendly, attentive, and quick to help, including with small practical matters such as seasickness medication. Captain Yanas is also noted for keeping people informed and adding humor during the route. That personal touch matters on a long boat day, especially for families and anyone who feels uncertain at sea.

Vathi on Kalymnos: a fjord, cliffs, and one quiet hour

The first island stop is Vathi, a village on Kalymnos. The approach is one of the prettiest parts of the route, with a natural fjord, steep rocky sides, gulfs, and caves around the water. Keep your camera ready as the boat enters the inlet.

You get free time to walk around the village and take in the setting. The stop is short enough that you should not expect a full tour of Kalymnos. Think of it as a taste of island life: a quiet street, local views, a few photo opportunities, and time to try a local specialty if you choose.

The schedule allows about an hour, though that can change. One reported day had less time at the first island because the captain spent extra time near dolphins. That trade was considered worthwhile, but you should understand the arrangement: wildlife and sea conditions can influence the timetable.

Vathi works well as the cultural part of the day. The other stops focus more on swimming, so this is your best chance to walk on land, see a traditional settlement, and get a sense of the smaller islands near Kos. It is not an attraction-packed stop, and that is part of its appeal.

Lunch onboard: simple Greek food with a vegetarian choice

After Kalymnos, you return to the boat for lunch. The standard plate includes pork or chicken souvlaki, salad, tzatziki, and bread. The vegetarian option replaces the meat with beans and dolmades.

I would describe the meal as straightforward rather than fancy. It is filling, familiar Greek food that fits a hot day at sea. Portions are reported as generous, and the lunch is especially good value because it is already included in the ticket price.

Vegetarians should identify themselves to the crew early. The arrangement is simple, and the crew has been helpful with advance food requests. The vegetarian plate can also suit vegans if you skip the tzatziki, according to the information provided. If you have another dietary need, the supplied details do not confirm a separate option, so ask before booking.

The meal is served onboard, saving you time and avoiding the need to find food during a short island stop. On the other hand, the food is not the reason to book the cruise. You are choosing convenience, a decent portion, and a Greek-style lunch rather than a restaurant meal.

Fish farms and the chance to see dolphins

After lunch, the boat passes nearby fish farms. This is the point when you should keep your eyes on the water. Wild dolphins have been seen jumping close to the boat, sometimes in groups, and the captain may make another turn if they appear.

There is no guarantee. Wildlife spotting depends on luck, timing, and sea conditions. Still, it is a genuine bonus rather than a staged show, and it adds an unexpected moment to an otherwise planned route. Flying fish have also been seen from the boat.

This part may alter the timetable. If the captain pauses for dolphins, you could receive less time at an island later. I think that is a fair trade for most people, but you should know about it before you go. If strict timing matters to you, this is not the most predictable excursion.

Plati: clear water and a boat-jump swim

Plati islet is the main swimming stop. The boat anchors or pauses in clear turquoise water, and you can jump from the boat for a swim around it. This is not a beach visit, so you should be comfortable entering the sea from the vessel.

The water is the star here. After the morning sailing and the walk at Vathi, a swim gives the day a welcome change of pace. You can listen to music, sit in the sun, or take a swim while the boat remains in the cove.

Wind can affect the plan. One day the boat could not dock at Plati because of the conditions, so the crew added another bay stop near Pserimos instead. That is a useful sign of sensible planning, but it also means the exact stop pattern is not fixed.

Bring your own towel, since towels are not included. Pack sunscreen and a hat, too. Sun exposure builds quickly on an open boat, even when the breeze makes the temperature feel pleasant.

Pserimos: a short island visit and more water time

The final island stop is Pserimos. You have about an hour to explore at your own pace, walk around, swim, or stop at a local restaurant. The island is smaller and quieter than Kos, and it gives you one last chance to step ashore before the return sailing.

Bring some cash. Card payment may not be accepted at restaurants on Pserimos, and you do not want to miss a drink or snack because you have relied entirely on a card. The supplied details do not give exact restaurant prices, so carry enough for whatever you may want to buy.

Pserimos is best approached without a long checklist. You are not coming here for major sights or a large town. The pleasure is the quiet setting, the bay, and a brief look at island life. If you prefer long beach time, the hour may feel short. If you like variety, the stop rounds out the day nicely.

From Pserimos, the boat sails back toward Kos. The final ride takes roughly 30 minutes according to the route information, though the total return time can vary with conditions and the day’s earlier stops.

Drinks, cocktails, and the onboard atmosphere

Drinks are not included, but you can buy them from the boat. Cocktails are offered at modest prices, with €6 given as a typical figure. The bar also makes the return sailing more pleasant, especially after swimming and walking in the heat.

This is not a party cruise in the usual sense. Music plays, and there is a happy-hour element, but the atmosphere is generally described as calm and family-friendly. You can expect a social boat with plenty of people, not a private sailing trip.

The boat can be crowded. One account describes seating that felt tighter than expected, with more people sharing a bench than the ideal arrangement. Other accounts describe plenty of space, so the experience may depend on the date, the number of bookings, and where you sit.

If you want the quietest possible day, a small private boat would suit you better. If you want a low-cost shared cruise with a friendly crew and a chance to meet other people, the Odyssey is a sensible choice.

Who will enjoy this cruise most

I would recommend this trip to you if you want a full day of variety without paying for separate transport and meals. It suits couples, families, swimmers, and first-time visitors who want a quick look at several islands near Kos.

Children can enjoy the swimming, music, island stops, and boat ride. Parents should bring extra sunscreen and hats, especially for children. The sea can be choppy, and the open deck offers limited shelter from sun and spray.

Swimmers will get the most from the day. The key highlights are the water stops, and the Plati stop in particular requires you to enter the sea from the boat. If you prefer to stay dry, you can still enjoy Vathi, Pserimos, the views, lunch, and the dolphin search, but the cruise is built around swimming.

The information gives conflicting guidance about mobility. It says the activity is wheelchair accessible, but it also says it is not suitable for people with mobility impairments. Since boarding, moving around a boat, and entering the water can be difficult, contact the operator before paying if accessibility is important to you.

Free cancellation is available up to 24 hours before departure, and you can reserve now and pay later. Those policies help if your Kos plans may shift, but you should still check the available start time before booking.

Should you book the Odyssey three-island cruise?

Book it if you want maximum variety for a low price: one fjord village, several swimming chances, a Greek lunch, possible dolphins, and two smaller islands in one day. The crew receives the strongest praise, and the combination of helpful service, affordable drinks, and flexible handling of sea conditions makes the cruise feel well managed.

Skip it if you dislike shared boats, need a rigid schedule, want a long visit on one island, or expect a quiet luxury sailing experience. The boat may be crowded, the music may not suit every taste, and wind can change the route.

For most people staying in Kos, I think this is a strong choice. Bring a towel, cash for Pserimos, sun protection, and a little patience about the timetable. Then settle in and let the day be what it is: a friendly, good-value ride through some beautiful water.
